Answers & Solutions:

1) Answer (E)

The conclusions talk about a relation between tables and bottles. Let’s bring a relation between these two using the given statements.

Some bottles are jugs and no jug is a plate => some bottles can be plates or no bottle is a plate

Some plates are tables => some bottles can be plates or no bottle is a plate.  — (1)

All cups are bottles and some bottles are jugs => Nothing about cups and jugs can be derived from this.

Since we cannot derive a conclusion between cups and jugs, it is not possible to derive a conclusion between cups and plates as well.

Hence option E, which says that some bottles can be plates or no bottle is a plate is the answer.

2) Answer (E)

The following are the two possibilities:

So, either I or III and II and IV follow.

3) Answer (A)

Birds is a subset of Horses, which is a subset of Tigers. So, conclusions I and III follow. But, conclusions II and IV need not follow.

4) Answer (C)

Based on the following Venn diagram, only conclusions 3 and 4 are implied.

5) Answer (A)

Based on the Venn diagram, none of the conclusions are implied by the statements.

6) Answer (A)

Some squares are circles and no circle is a triangle => Some squares are not triangles => Conclusion 1 follows

No line is a square => No relation can be brought between line and circle => Conclusion 2 does not follow.

7) Answer (D)

Some squares are circles and no circle is a triangle => Some squares are not triangles => Some squares being triangles is a possibility => Conclusion 1 does not follow

No line is a square and some square are circle => Some lines being circles is a possibility => Conclusion 2 does not follow

8) Answer (E)

All songs are poems and all poems are rhymes => All songs are rhymes

No rhyme is a paragraph => No song is a paragraph => Conclusion 1 follows

All poems are rhymes and no rhyme is a paragraph => No poem is a paragraph => Conclusion 2 follows

9) Answer (B)

All poems are rhymes does not imply that all rhymes are poems. The correct conclusion is Some Rhymes are poems. Conclusion 1 does not follow.

All songs are poems and all poems are rhymes => All songs are rhymes => Conclusion 2 follows

10) Answer (E)

All drops are stones => Some stones are drops. So, conclusion II follows.

Some dews are drops => Some drops are dews. But all drops are stones. => Some dews are stones. So, conclusion I follows.

Option e) is the correct answer.

11) Answer (B)

No parachute is an airplane and all airplanes are helicopters doesn’t give an indication about the relation between parachutes and helicopters. So, all parachutes are helicopters is not contradicted in the statements.

12) Answer (E)

From the given statements, no glider is an airplane is implied but no relation is established between gliders and helicopters. So, all gliders being helicopters is a possibility.

13) Answer (A)

Some mails are chats. There is a possibility that all mails are chats. All updates are chats. So, if mails is a subset of updates, which in turn is a subset of chats, the conditions still hold true. So, conclusion I follows. Conclusion II is not necessarily true as there might be some intersection between mails and updates.

14) Answer (B)

Some metals are paper and all paper are glass => Some metals are glass or some glass are metal. So, conclusion II follows. No glass is metal need not be true. So, the correct answer is option b).

15) Answer (A)

Consider the following diagram:

From this we can see that all stones being glass is a possibility and no stone is paper need not be true. So, option a) is the correct answer.

16) Answer (D)

Some exams are tests and no exam is a question.

Nothing can be built between tests and questions from this information.

Some exams are tests doesn’t mean some tests are not exams because this could be a case where all tests are exams.

Hence neither of the statements is true.

17) Answer (B)

All forces are energies and all energies are powers => all forces are powers. => conclusion 1 is wrong

No power is a heat and all forces are powers => No heat is force.

Only conclusion 2 follows.

18) Answer (A)

All forces are energies, all energies are powers and no power is heat => no energy is heat => Conclusion 1 is correct

No force is heat => Conclusion 2 is wrong.

Hence only conclusion 1 follows.

19) Answer (E)

All plastics are notes and no note is a coin => no coin is plastic => Conclusion 1 follows.

Some coins are metals => Some notes being metals is a possibility => All plastics being metals is a possibility => Conclusion 2 follows.

=> Both follow

20) Answer (D)

No plastic is a coin and some coins are metals => Some metals being a plastic is a possibility => Conclusion 1 is wrong

All plastics are notes does not imply all notes are plastic => Conclusion 2 is wrong

Hence neither of the conclusions is correct
